The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent.
<h3>How is the lac operon triggered by E. coli?</h3>
The lac operon of E. coli contains genes related to lactose metabolism. Only when lactose and glucose levels are low does it manifest symptoms. Two regulators that control the operon's "on" and "off" states in response to lactose and glucose concentrations are lac repressor and catabolite activator protein (CAP).
<h3>Why does E. coli prefer glucose to lactose?</h3>
Because it promotes quicker development than other sugars and is the first sugar to be consumed in sugar combinations, glucose is frequently the best carbon source for E. coli.
